These are API PCMO servvice category oils - dont be confused by motorcycle pictures on the oil bottle - only the certs matter, not ad copy or pictures!!! Most OIL Guys here still dont get this SIMPLE fact and are afraid to run "motorcycle" oil in a car engine. IN most cases this oil is much more robust than ANY current ISACL approved lube.
DOH!
How would you know? You are unable to keep a car longer than a year...maybe two before the valves start making noise or something else blows out. You are absolutely the last guy I would ask about oil.

The seal technology in the 1970's and 1980's is not very good at handling synthetic oil. You have a high chance of getting leaks based on the cleaning of syn oil over time. Engine sealing technology changed radically in the 1990-1994 time frame. So anything pre-1993 would be best served by dino.
That is entirely untrue. What usually happens is that old gaskets, particularly cork valve cover gaskets, become rock-hard and stop doing their job. But deposit build-up along their edges has prevented leaks. When that build-up gets cleaned-off, well, the leaks begin. Even a new set of cork gaskets fixes the problem.
I experienced that in my Mustang. A new set of valve cover gaskets, and it was golden.
Properly formulated lubricants are designed to be compatible with, and not harm all major gasket and seal materials, even those used 50+ years ago. The base oil is irrelevant because of this.
You don't know what you are talking about either.

Oh. That old myth. This engine might very well leak through the seals, but it won't have anything to do with the base stock of the oil.
Not a myth. Call Federal Mogul or FNOK and ask any of the engineering people who deal with engine sealing.

LOL!
How many engines have you had apart there champ? I assume since you couldn't find the power steering reservoir on your vehicle that has electric power steering, that a guess close to "ZERO" would be about accurate, am I right?
I have a LOT of experience with extremely old engines. And when I say extremely old, I'm talking 1930's, 40's 50's....etc. We literally had a FLEET of antique boats when I was growing up and I was heavily involved in their maintenance.
I've also posted the 302 builds I've been involved with on this site (80's engines).
So unless you can tell me that you are more qualified than I am to relate to actual experience on this topic, I suggest keeping your baseless criticisms to yourself.

Doog has his sights trained on anyone who posts. Look out.
He may be right about arco but that's arco's problem as he has to pay for replacements so I say rock on.
If I were Arco I would be ripping apart every blown engine just to see what broke,and I like tearing things apart.
As far as overkill is concerned,doogie has lost his mind. I can guarantee you overkill has researched and has informed himself and his posts reflect that he has done more than just a google search. Overkill is not the type to allow himself to be corrected. So he posts correctly,the first time.
K. So back on topic. Oil in a 454. My uncle has a 70 chevelle with an LS-6 454. He uses pyb 10w-30 and has since he bought it brand new in 1970. Car has 70000 original miles and boys its already willed to me.
It's the baddest muscle car Chevrolet ever built. The last of the fire breathing muscle cars to roll off the line in Detroit and it looks exactly like it did the day he took delivery.
Yeah so pyb,changed every 3000 miles due to fuel dilution on the massive carb up top.

The odds of being able to talk to an actual Engineer from any of the gasket/seal companies is about as likely as calling ExxonMobil and speaking to a lubrication Engineer.
You talk to a "Customer Service Representative" that will tell you all kinds of exciting stuff (I cite the varied responses we've got from the oil companies over the years that often clash with other responses from the same company.... just from a different rep as an example here) that may or may not reflect the position of the company they represent.
I would LOVE to see an actual statement, authorized by a company like Felpro, on this topic. Because it completely contradicts the official statements made by the oil companies as well as the experience of those who have actually done what is being argued against here and observed no issues.

-- Patrick Poe, Norman, OK
Answer:
Mobil 1 High Mileage is formulated with seal swells that will help eliminate leakage. We recommend you switch to Mobil 1 High Mileage for your vehicle. If your vehicle is not leaking now, switching to synthetic will not suddenly cause it to leak. Switching to a synthetic now may help you to maximize the life of your Expedition. If your vehicle is leaking before you change to synthetic, it will probably continue to leak with synthetic. However, by using Mobil 1 High Mileage it is possible that leakage could be eliminated or reduced. It depends on what is causing the leak.

I'm trying to figure out what to do to my '98 BMW 740i with 126,000 miles which I'd like to keep until I get it to at least 200,000 miles.
-- Kent Bauman, Tucson, AZ
Answer:
Synthetic oils meeting OEM (original equipment manufacturer) and Industry specifications do not cause leaks as they are tested to ensure that they are fully compatible with the elastomer materials from which automotive seals and gaskets are made. We are not aware of a controlled study on this topic.

The myth is rooted in the idea that synthetic oil is “slipperier,” lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue. Synthetic oils will enhance the engine protection in older vehicles just as they do for new engines.

In my time, I've built... oh, I don't know. At least a thousand engines. I never, ever, ever, even at the peak of the PAO-synthetic debacle, worried about some obscure combination of gasket and oil that would magically cause a leak. In my opinion, engines that leaked with early synthetics were already leaking, they just leaked MORE once their seals "un-swelled," which has always been my understanding of what was going on with the PAO's.

Synthetic oils are designed to carry away deposits, so it is possible to expose marginal seals after those pre-existing deposits are removed. If an engine leaks after putting Royal Purple or any other synthetic in, the oil is probably not causing the leak, it is exposing an existing leak. In these cases or in older cars where this might be a concern, it may be best not to recommend a very lightweight oil. In the long run, it is better to replace a faulty gasket than to leave those deposits in the engine.

My experience is focused mostly on the 302 SBF. But the rest of it is pretty varied
Gray, Chris-Craft, Chrysler, Scripps, Dispro....etc. We had pretty much at least one of everything... sometimes a lot more than one
